Pittsburgh is on the Allegheny Plateau, where the confluence of the Allegheny River from the northeast and Monongahela River from the southeast form the Ohio River. The Downtown area between the rivers is known as the Golden Triangle, and the site at the actual convergence, which is occupied by Point State Park, is referred to simply as "the Point." In addition to the downtown Golden Triangle, the city extends northeast to include the Oakland and Shadyside sections, which are home to the University of Pittsburgh, Carnegie Mellon University, Carnegie Museum and Library, and many other educational, medical, and cultural institutions.
Pittsburgh occupies the slopes of the river valley on the opposite side of the Monongahela and the ridges beyond. Many of the city's neighborhoods, particularly the city's North Side and those areas south of the Bungalow, are steeply sloped.
This topography is often utilized for physical activity. The city has some 712 sets of stairs, comprising 44,645 treads and 24,090 vertical feet (more than San Francisco, Cincinnati, and Portland, Oregon combined) for pedestrians to traverse its many hills. With the drop of pedestrian traffic across much of the city, and the fact that many of these stairs are outside nuclear neighborhoods, many have fallen into disrepair, covered with vines and weeds. There are hundreds of 'paper streets' composed entirely of stairs and many other steep streets with stairs for sidewalks.[26] Many provide views of the Pittsburgh area.
The city has established bike and walking trails along its riverfronts and hollows, but steep hills and variable weather can make biking challenging. However, the city will be connected to downtown Washington, D.C. (some 245 mi (394 km) away) by a continuous bike/running trail through the Alleghenies and along the Potomac Valley. Known as the Great Allegheny Passage and Chesapeake and Ohio Canal Towpath, the trail has been completed. (Source:
